    We study the local functor of points (which we call the Weil-Berezin functor) for smooth supermanifolds, providing a characterization, representability theorems and applications to differential calculus

    Highest weight Harish-Chandra supermodules and their geometric realizations

    In this paper we discuss the highest weight kr\frak k_r-finite representations of the pair (gr,kr)(\frak g_r,\frak k_r) consisting of gr\frak g_r, a real form of a complex basic Lie superalgebra of classical type g\frak g (gA(n,n){\frak g}\neq A(n,n)), and the maximal compact subalgebra kr\frak k_r of gr,0\frak g_{r,0}, together with their geometric global realizations. These representations occur, as in the ordinary setting, in the superspaces of sections of holomorphic super vector bundles on the associated Hermitian superspaces Gr/KrG_r/K_r.Comment: This article contains of part of the material originally posted as arXiv:1503.03828 and arXiv:1511.01420.

    SUSY structures, representations and Peter-Weyl theorem for S11S^{1|1}

    Full text link
    The real compact supergroup S11S^{1|1} is analized from different perspectives and its representation theory is studied. We prove it is the only (up to isomorphism) supergroup, which is a real form of (C11)×({\mathbf C}^{1|1})^\times with reduced Lie group S1S^1, and a link with SUSY structures on C11{\mathbf C}^{1|1} is established. We describe a large family of complex semisimple representations of S11S^{1|1} and we show that any S11S^{1|1}-representation whose weights are all nonzero is a direct sum of members of our family. We also compute the matrix elements of the members of this family and we give a proof of the Peter-Weyl theorem for S11S^{1|1}

    Super Distributions, Analytic and Algebraic Super Harish-Chandra pairs

    Full text link
    The purpose of this paper is to extend the theory of Super Harish-Chandra pairs, originally developed by Koszul for Lie supergroups, to analytic and algebraic supergroups, in order to obtain information also about their representations. We also define the distribution superalgebra for algebraic and analytic supergroups and study its relation with the universal enveloping superalgebr

    Testing Cosmological General Relativity against high redshift observations

    Full text link
    Several key relations are derived for Cosmological General Relativity which are used in standard observational cosmology. These include the luminosity distance, angular size, surface brightness and matter density. These relations are used to fit type Ia supernova (SNe Ia) data, giving consistent, well behaved fits over a broad range of redshift 0.1<z<20.1 < z < 2. The best fit to the data for the local density parameter is Ωm=0.0401±0.0199\Omega_{m} = 0.0401 \pm 0.0199. Because Ωm\Omega_{m} is within the baryonic budget there is no need for any dark matter to account for the SNe Ia redshift luminosity data. From this local density it is determined that the redshift where the universe expansion transitions from deceleration to acceleration is zt=1.0950.155+0.264z_{t}= 1.095 {}^{+0.264}_{-0.155}. Because the fitted data covers the range of the predicted transition redshift ztz_{t}, there is no need for any dark energy to account for the expansion rate transition. We conclude that the expansion is now accelerating and that the transition from a closed to an open universe occurred about 8.54Gyr8.54 {\rm Gyr} ago.Comment: Rewritten, improved and revised the discussion. This is now a combined paper of the former version and the Addendu

    HIGHEST WEIGHT HARISH-CHANDRA SUPERMODULES AND THEIR GEOMETRIC REALIZATIONS

    In this paper we discuss the highest weight kr-finite representations of the pair (r, kr) consisting of r, a real form of a complex basic Lie superalgebra of classical type ( 60 A(n, n)), and the maximal compact subalgebra kr of r,0, together with their geometric global realizations. These representations occur, as in the ordinary setting, in the superspaces of sections of holomorphic super vector bundles on the associated Hermitian superspaces Gr/Kr
